FIELD OF THE INVENTION

The present invention relates to the field of travel luggage, and more particularly to a stackable luggage.

BACKGROUND

Everyday, countless consumers climb into automobiles, buses and airplanes and embark on business trips and family vacations. Whether traveling across state lines in order to visit a favorite relative, trekking across country for a relaxing stay at a beach front resort, or climbing aboard a 747 for an important business meeting, spending time away from home is a fact of life for millions of people. Regardless if one travels for business or pleasure, most consumers do not leave home without first packing personal belongings necessary for the trip. Changes of clothing, shoes, toiletries, hair dryers and personal mementos are but a few of the many items most people pack into a suitcase and take with them on the road.

Presently, most suitcases include at least one pair of wheels attached to the bottom of the suitcase and a handle or pull-bar attached to the top or to one of the sides of the suitcase. The wheels and handle allow the suitcase to be pulled and easily transport along a supporting surface. While this is convenient and works well, a problem occurs in the case where an individual traveler has more than one large piece of luggage. This problem may be overcome by placing one luggage on top of another but this solution does not prevent the luggage from falling off.

Several patents and patent applications address this problem.

U.S. Pat. No. 7,717,440 discloses a manually operable luggage cart including a central and unitary storage chamber with planar top and bottom surfaces. The assembly further includes a handle that is pivotal between rectilinear oblong displaced positions extending parallel and diagonal to a longitudinal length of the storage chamber, a plurality of casters rotatably connected to the storage chamber, and a mechanism for automatically biasing the casters between exposed and retracted positions from the bottom surface of the storage chamber when the handle is pivoted between the parallel and diagonal positions and about a curvilinear path defined adjacent to the proximal end of the storage chamber. The adaptable luggage cart further includes a plurality of straps.

U.S. Pat. No. 5,167,306 discloses a combined luggage and cart apparatus including a cart disposed within a luggage case. The cart has tubular legs joined at one end by a base plate. A U-shaped handle is inserted in the legs and a locking arrangement prevents separation of the handle from the legs, once inserted. The locking arrangement includes a sleeve inserted in the legs, and a split ring insertable through the sleeve and held captive on the handle. The sleeve includes a locking tab to engage the legs, and the split ring engages the sleeve when the handle is placed in use.

US patent application 2005/0145458 discloses a large capacity piece of luggage that complies with the maximum size requirements of the airlines with a plurality of special features. These include an infinitely variable position handle used to either pull or push the luggage on two large curb climbing wheels. The handle can rotate in a horizontal plane from one of its supporting vertical members to provide a temporary closet rod for hanging clothes from hangers. The handle also includes hooks to hang clothes from. Also included is a telescoping integral luggage cart with steerable auxiliary wheels. Other features include fixed, but removable identification plaques that are externally visible, an externally visible large figure digital travel alarm clock, an integral fold out table disposed within the cover of the luggage and supported thereby, and an externally accessible freshen kit and utility drawer. The invention further includes a chest of drawers feature which allows interior bags to be used either as drawers or to be removable from the parent bag and used as separate luggage to double the capacity of the original piece of luggage. Finally, on the back of the luggage is a pouch type of an enclosure similar to that which are on the backs of front car seats which may be accessed from the upper side to store a newspaper, magazines and the like.

US patent application 2004/0000458 discloses a combination suitcase and baggage cart having a first case for storing items. A second case is retractably coupled to the first case and is also used for storing items. A set of wheels is coupled to the first case and the second case for moving the combination suitcase and baggage cart. Retaining fences are retractably coupled to the first case and the second case for holding items on the combination suitcase and baggage cart. A handle is coupled to the combination suitcase and baggage cart for pulling combination suitcase and baggage cart.

US patent application 2006/0175170 discloses a convertible luggage device including a retractable handle assembly and at least one pair of extendable wheels. Included is a brake system operating to lock at least one of the wheels. In one aspect, the device forms a stroller. In another aspect, the device includes straps for engaging a car seat or a basket for receiving luggage or other items. By embodying a broad wheel base, the arrangement provides a stable platform for pushing or pulling luggage or for performing as a stroller.

US patent application 20090315284 discloses a luggage case which is convertible between a first configuration similar to a suitcase and a second configuration similar to a wheeled cart. The luggage case may have wheels and a pivotal handle. The pivotal handle may be supported by a strut pivotally fixed thereto at one end and arranged at the other end to slide along a groove in a guide track fixed to the luggage case. The strut may be entrapped to stop at a predetermined location along the groove with the handle fixed at an angle suitable for pushing the luggage case on its wheels.
